| 摘 要： | 提出一个新颖的模型来描述受激散射过程.由于光与介质相互作用会引起介质内折射率变化,我们引入德拜弛豫关系来描述折射率对光场的响应,通过求解非线性耦合波方程得到了受激瑞利散射的增益因子,并分析了德拜弛豫常数对二波之间能量耦合的影响,以及导致解受激散射的各种物理机制.

| Abstract: | Anovel model to describe the dynamic behavior of backward sti mulated scattering is presented.By endowing specific physical meanings of Debye Relaxation relation of electrostriction and thermal effect,the mechanisms of sti mulated scattering process could be easily deduced.An effective phase lag constantbetween the incident beamand the backward scattering beamis also introduced here and its influence onenergy couplingis detailed analyzed.The results achieved fit well with the previous theoretical treat mentand experi mental data. |

| Keywords: | sti mulated scattering debye relaxation two-wave mixing |
